Gowanda’s 28M222G is a high-quality, reliable molded unshielded RF coil designed for COTS applications. Weighing 2.65 grams, it features dimensions of 22.86 × 7.137 × 7.137 mm and is part of the 28M series. This through-hole technology (THT) component offers an inductance of 22 µH with a minimum Q factor of 50, tested at a frequency of 2.5 MHz. It has a direct current resistance (DCR) of 0.295 Ω and a self-resonant frequency (SRF) of 24 MHz, with a current rating of 0.725 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, and it has a tolerance of ±2%. The termination type is lead-based with a Sn63Pb37 finish, and it utilizes a powdered iron core. Operating within a temperature range of -55°C to +125°C, it is fungal inert and has a moisture sensitivity level (MSL) of 1, packaged in tape and reel (T&R) format.
